RSLogix 5000 “Serial” Logic
RSLogix 5000 allows the use of “serial” logic that does not conform to traditional, electrical ladder logic. For example, both of the rungs shown below are valid in RSLogix 5000.
Troubleshooting – Make Sure You Have a Clear Goal and a Concise Plan
Successful troubleshooting isn't always about knowing the detailed specifications of a device, or understanding the nuances of a particular PLC. Sometimes, it is simply about being able to see the big picture.
Adding Tags and the Tag Database in RSView32
One of the basic skills required to program any HMI or SCADA is the understanding of tags and the tag database. Here is a quick lesson on building the tag database in RSView32.
Addressing in RSLogix 5000
Before you can program any PLC system, you have to understand how the addressing is done in that particulaur PLC. I have included a actual screenshot from RSLogix 5000 below that shows examples of addressing in RSLogix 5000. Read on to get the details.
Ladder Logic and the Dialect of PLCs
Ladder logic is a programming language, like Visual Basic or C. When you learn any language, it is always important to understand the basic terms. If you are just getting started, here are a few terms you should know. These apply to any PLC.
Catch The Wind And Crank Up Your Turbine
Wind power has been growing at a pace that rivals that of the solar industry. The worldwide generating capacity of wind turbines has grown more than 25% every year for the past decade, reaching nearly 60,000 MW in early 2006. In Europe, the growth has been phenomenal. In 1994, the total installed wind generated power capacity of the European Union nations was 1700 MW. In 2005, wind generators produce more than 40,000 MW.
